What is Relationship: Definition and 1000 Discussions

An intimate relationship is an interpersonal relationship that involves physical or emotional intimacy. Although an intimate relationship is commonly a sexual relationship, it may also be a non-sexual relationship.
Emotional intimacy involves feelings of liking or loving one or more people, and may result in physical intimacy. Physical intimacy is characterized by romantic love, sexual activity, or other passionate attachment. These relationships play a central role in the overall human experience. Humans have a general desire to belong and to love, which is usually satisfied within an intimate relationship. Such relationships allow a social network for people to form strong emotional attachments.

    What is the relationship between refraction and giant waves in Nazaré?

    The waves of Nazaré start because of a storm in the open sea. The winds cause a disturbance on the surface, transformed into energy. When the depth is great, the propagation of the waves (energy) is practically constant. As they approach the coast, therefore in shallower places, the wave length...

    Relationship between electric and magnetic fields

    So, basically I can follow the math deriving E/B = c from Maxwell. And I can calculate B and H from I: H = I/2*pi*r and B=uH. Easy. So, for example I take a 2000 A, 50 Hz, current and a distance of 2 meter from that current in a round conductor. H and B are set: H = 160 A/m and B = 0,2 mT...

    Damped Oscillation Amplitude Decrease vs. Mass Relationship

    so what I did was e^-(1/10.1)=0.9057 and e^-(1/14.8)=0.93466 Then 0.93466/0.9057 = 1.03198, so the heavier mass dampens 1.03 times more than the lighter mass. If the lighter mass decreases the oscillation to 72.1%, then the heavier mass would be 72.1%*1.03198 = 74.4, but this is wrong. It...
